Abstract EN
A parametric study of nonlinear seismic response analysis of transmission line structures subjected to earthquake loading is studied in this paper.
The transmission lines are modeled by cable element which accounts for the nonlinearity of the cable based on a real project.
Nonuniform ground motions are generated using a stochastic approach based on random vibration analysis.
The effects of multicomponent ground motions, correlations among multicomponent ground motions, wave travel, coherency loss, and local site on the responses of the cables are investigated using nonlinear time history analysis method, respectively.
The results show the multicomponent seismic excitations should be considered, but the correlations among multicomponent ground motions could be neglected.
The wave passage effect has a significant influence on the responses of the cables.
The change of the degree of coherency loss has little influence on the response of the cables, but the responses of the cables are affected significantly by the effect of coherency loss.
The responses of the cables change little with the degree of the difference of site condition changing.
The effect of multicomponent ground motions, wave passage, coherency loss, and local site should be considered for the seismic design of the transmission line structures.
